Presbyterian Healthcare Services, one of New Mexico’s largest health systems, is discontinuing most of its Medicare Advantage plans for the 2027 plan year, a decision that leaves about 30,000 members needing to line up new coverage. The health system announced the move in June 2026, tying it to more than $59 million in losses on the plans in 2025. Coverage for the rest of 2026 is unaffected, but affected members will have to choose a replacement plan during this fall’s enrollment window for the change that takes effect January 1, 2027.
What Presbyterian is ending and what it is keeping
The health system will drop most of its individual Medicare Advantage offerings across New Mexico, according to reporting on the announcement. About 30,000 people enrolled in those plans will be affected, making it one of the larger single-market Medicare Advantage exits to hit the state’s older residents in recent memory.
Not everything is going away. Presbyterian said it will continue to offer its Medicare Advantage dual special needs plans, known as D-SNPs, which serve people who qualify for both Medicare and Medicaid. Members in those plans are not part of the group being cut, though everyone enrolled in the discontinued products will need to act before the new plan year begins.
The company framed the decision as a financial one driven by rising medical costs, significant regulatory changes, and the administrative complexity of running the plans. It also announced that roughly 150 administrative employees would be laid off as part of the restructuring, a sign that the retreat reaches beyond the insurance products themselves.

Why the plans lost money and what that signals
The $59 million figure is the heart of the decision. Presbyterian said the discontinued Medicare Advantage plans contributed to more than that amount in losses in 2025, a level the nonprofit system concluded it could not keep absorbing. The company’s account of rising costs and regulatory pressure echoes strains that have pushed other insurers to trim their Medicare Advantage footprints as well.
Medicare Advantage plans are paid a fixed amount per member by the federal government and profit only when that payment exceeds the cost of care. When medical spending climbs faster than those payments, plans that once looked sustainable can turn into money-losers quickly, especially in a smaller market where a single system carries much of the enrolled population. Presbyterian’s exit reflects that math playing out at scale.
For New Mexico’s older residents, the withdrawal narrows the menu of local options at a time when Medicare Advantage has been the default choice for a growing share of beneficiaries. State lawmakers pressed the company over the changes after the announcement, and local coverage noted the scramble the decision would create for tens of thousands of enrollees heading into the fall.
Presbyterian is not alone in pulling back. Several national insurers trimmed or exited Medicare Advantage markets for the 2026 and 2027 plan years, pointing to the same mix of rising care costs and tighter federal payment and coding rules. What makes the New Mexico case sting is concentration: in a state where one nonprofit system has long been a dominant Advantage carrier, a single exit removes far more of the local market at once than a comparable move by a national insurer would in a larger, more crowded state.
The enrollment window that decides members’ 2027 coverage
Members whose plans are ending get a defined window to act. Medicare’s annual open enrollment period runs from October 15 through December 7, and choices made during it take effect January 1. A Presbyterian enrollee who does nothing risks losing the plan entirely rather than being automatically moved into a comparable one, which makes the fall window the practical deadline for keeping coverage intact.
The options are not limited to another Medicare Advantage plan. Affected members can switch to a different Advantage insurer still operating in their county, or return to Original Medicare and, in many cases, pair it with a standalone Part D drug plan and a Medigap supplement. Because a Medicare Advantage carrier’s departure can qualify enrollees for a special enrollment period, some may also have added flexibility to buy a Medigap policy that could otherwise be harder to obtain.
The Medigap angle carries a catch worth weighing. Outside of a guaranteed-issue window, insurers in most states can screen applicants for health conditions and charge more or decline coverage, which can make returning to Original Medicare harder for someone who has been in an Advantage plan for years. A carrier’s withdrawal is one of the situations that can open a guaranteed-issue right, so the members losing Presbyterian coverage may have a narrower and more valuable opening to buy a supplement than they would in an ordinary year.
What does not change is the 2026 coverage members already hold, which continues through the end of the year as reported in local coverage of the announcement. The decision that lands next is which plan replaces it, and for roughly 30,000 New Mexicans that choice arrives during a single fall enrollment window rather than at their own pace.
